BACKGROUND OF THE INVENTION

This invention relates to novel 3-[2-hydroxy-4-(substituted)phenyl]-4(or 5-)-substituted)cycloalkanones and cycloalkanols useful as analgesic agents and as anti-emetic agents; to derivatives thereof, intermediates therefore and processes for their preparation.

Despite the current availability of a number of analgesic agents, the search for new and improved agents useful for the control of broad levels of pain and accompanied by a minimum of side-effects continues. The most commonly used agent, aspirin, is of no practical value for the control of severe pain and is known to exhibit various undesirable side-effects. Other analgesic agents, such as meperidine, codeine, and morphine, possess addictive liability. The need for improved and potent analgesic agents is, therefore, evident.

Compounds having utility as analgesics, tranquilizers, sedatives, antianxiety agents and/or as anticonvulsants, diuretics and antidiarrheal agents are described in Belgian Patents Nos. 870,404 and 870,402, both granted Mar. 12, 1979. Belgian Patent No. 870,404 describes 3-[2-hydroxy-4-(substituted)phenyl]cycloalkanones and cycloalkanols which may have at the 4-position of the cycloalkanone or cycloalkanol residue, an alkyl, alkenyl, phenyl or phenylalkyl substituent; or, at the 5-position, an alkyl substituent, and Belgian Patent No. 870,402 discloses certain 2-(acyclic substituted)phenols; namely, 2-(hydroxyalkyl)-4-(substituted)phenols and 2-(oxoalkyl)-4-(substituted)phenols.

U.S. Pat. No. 3,576,887, issued Apr. 27, 1971, discloses a series of 1-(1'-hydroxy)alkyl-2-(o-hdroxyphenyl)cyclohexanes which exhibit central nervous system depressant properties.

Our concurrently filed application, Ser. No. 189,402, filed Sept. 19, 1980, now U.S. Pat. No. 4,285,867, issued Aug. 25, 1981, entitled "Pharmacologically Active 4-[2-Hydroxy-4-(Substituted)phenyl]Naphthalen-2(1H)-ones and 2-ols, Derivatives Thereof and Intermediates Therefore," describes a series of 4-[2-hydroxy-4-(substituted)phenyl]naphthalen-2(1H)-ones and 2-ols useful as CNS agents and as antiemetic agents.

U.S. Pat. No. 3,974,157 describes 2-phenylcyclohexanones which can be substituted in the phenyl ring with up to two alkyl, hydroxy or alkoxy groups as intermediates for preparation of 1-(aminoalkyl)-2-phenylcyclohexanols useful as analgesics, local anesthetics and antiarrhythmics.

DETAILED DESCRIPTION OF THE INVENTION

The compounds of this invention having formulae I or II wherein Y is --CH(R₂ ")CH(R₂)-- are prepared from the appropriate 2-bromo-5-(Z-W substituted)phenol by a series of reactions which comprises as the first step protection of the phenolic group. Suitable protecting groups are those which do not interfere with the subsequent reactions and which can be removed under conditions which do not cause undesired reactions at other sites of said compounds or of products produced therefrom. Representative of such protective groups are those phenolic protecting groups described by Haslam in Chapter 4 of "Protective Groups in Organic Chemistry," Edited by J. F. W. McOmie, Plenum Press, London and New York (1973). Favored groups are methyl, ethyl, tetrahydropyranyl, benzyl or substituted benzyl wherein the substituent is, for example, alkyl having from one to four carbon atoms, halo (Cl, Br, F, I) and alkoxy having from one to four carbon atoms. The ether protecting, or blocking, groups can be removed through the use of hydrobromic acid in acetic acid or hydrobromic acid, 48% aqueous. The reaction is conducted at elevated temperatures and desirably at the reflux temperature. However, when Z is --(alk₁)_(m) --O--(alk₂)_(n) --, acids such as polyphosphoric acid or trifluoroacetic acid must be used to avoid cleavage of the ether linkage. Other reagents such as hydriodic acid, pyridine hydrochloride or hydrobromide can be used to remove protecting ether groups such as methyl or ethyl groups. When the protecting groups are benzyl or substituted benzyl groups, they can be removed by catalytic hydrogenolysis. Suitable catalysts are palladium or platinum, especially when supported on carbon. Alternatively, they can be removed by solvolysis using trifluoroacetic acid. A further procedure comprises treatment with n-butyllithium in a reaction-inert solvent at room temperature.

The exact chemical structure of the protecting group is not critical to this invention since its importance resides in its ability to perform in the manner described above. The selection and identification of appropriate protecting groups can easily and readily be made by one skilled in the art. The suitability and effectiveness of a group as a hydroxy protecting group are determined by employing such a group in the herein-illustrated reaction sequences. It should, therefore, be a group which is easily removed to regenerate the hydroxy groups. Methyl, tetrahydropyranyl and benzyl are preferred protecting groups since they are readily removed.

The protected 2-bromo-5-(Z-W substituted)phenol is then reacted with magnesium in a reaction-inert solvent and generally in the presence of a promoter, e.g., cuprous salts such as the chloride, bromide and iodide (to promote 1,4-addition) with the appropriate 4-R₂ '-2-cycloalken-1-one (e.g., 4-R₂ '-2-cyclohexen-1-one) wherein R₂ ' is alkenyl or X'-substituted alkyl wherein X' is X or a precursor therefor, e.g., --Obenzyl as precursor for --OH; --CH(OCH₃)₂ or --HCOCH₂ CH₂ O as precursor for --CHO. Suitable reaction-inert solvents are cyclic and acyclic ethers such as, for example, tetrahydrofuran, dioxane and dimethyl ether of ethylene glycol (diglyme). The Grignard reagent is formed in known manner, as, for example, by refluxing a mixture of one molar proportion of the bromo reactant and two molar proportions of magnesium in a reaction-inert solvent, e.g., tetrahydrofuran. The resulting mixture is then cooled to about 0° C. to -20° C. The amount of cuprous iodide used is not critical, but can vary widely. Molar proportions ranging from about 0.2 to about 0.02 moles per mole of bromo reactant afford satisfactory yields of the cycloalkanone wherein the phenolic hydroxy group is protected (formula II, R₁ =a protecting group).

Alternatively, compounds of formulae I and II are prepared by reaction of the copper derivative of an appropriate 3-(Z-W-substituted)phenol, the hydroxy group of which is suitably protected, with an appropriate 4- or 5-substituted cycloalk-2-en-1-one in a reaction-inert solvent at a low temperature, e.g., below -20° C. Suitable protecting groups are those enumerated above except, of course, benzyl or substituted benzyl which would be removed during preparation of the precursor lithio derivative of the copper 3-(Z-W)phenol. An especially useful protecting group for this alternative methodology is the tetrahydropyranyl group. Said protecting group is easily introduced into the phenol reactant, is stable to the conditions of subsequent reactions in which said protected compound serves as intermediate, and is conveniently removed by hydrolysis.

The copper derivative of the 3-(Z-W-substituted)-phenol is prepared from the lithio derivative of said phenol by treatment of said lithio derivative with 1-hexyne copper. It undergoes 1,4-addition to the conjugated C═C-C═O system of the cycloalk-2-en-1-one reactant, in contrast to the characteristic 1,2-addition of the corresponding lithio derivative.

This alternative 1,4-addition step, of course, gives rise to the same compounds as does the above-described Grignard reaction. It generally affords better yields of the formulae II and I compounds

It will be noted that in a preparation of a compound of formula I herein wherein each of R and R₁ is hydroxy, Y is --CH₂ CHR₂ --, R₂ is (CH₂)₃ OH and Z-W is 1,1-dimethylheptyl, the particular sequence exemplified (Examples 91-96) utilizes intermediates wherein the Z-W group is 1,1-dimethyl-2-heptenyl and which is hydrogenated in the last step of the sequence to 1,1-dimethylheptyl. Reduction of said 1,1-dimethyl-2-heptenyl group can, of course, be accomplished at any stage of the sequence if desired, i.e., it need not be delayed until the final step.

The protected cycloalkanone is then treated with an appropriate reagent to remove the protecting group, if desired. The benzyl group is conveniently removed by the method described above. If the protecting group is an alkyl group (methyl or ethyl), it is removed by the above-mentioned methods or by treatment with, for example, pyridine hydrochloride. The tetrahydropyranyl group is removed by means of an acidic reagent.

When the appropriate 4-R₂ '-2-cycloalken-1-one is not aviilable or is not readily obtainable by known methods, compounds of formula II wherein R₂ is oxo-substituted (C₁₋₆)alkyl, and especially those wherein R₂ is formyl, serve as intermediates for all other formulae I and II compounds.

When R₂ ' is an alkenyl group, the cycloalkanones (formula II) thus produced serve as intermediates for preparation of the corresponding cycloalkanones wherein R₂ is substituted alkyl as defined above.

The cycloalkanol compounds having formula I are prepared from the protected cycloalkanones by reduction. Sodium borohydride is favored as reducing agent in this step since it not only affords satisfactory yields of the desired product, but retains the protectin group on the phenolic hydroxy group, and reacts slowly enough with hydroxylic solvents (methanol, ethanol, water) to permit their use as solvents. Temperatures of from about -40° C. to about 30° C. are generally used. Lower temperatures, even down to about -70° C., can be used to increase selectivity of the reduction. Higher temperatures cause reaction of the sodium borohydiide with the hydroxylic solvent. If higher temperatures are desired, or required for a given reduction, isopropyl alcohol or the dimethyl ether of diethylene glycol are used as solvents. Sometimes favored as reducing agent is potassium tri-sec-butyl borohydride since it favors stereoselective formation of the trans-1,3-phenylcycloalkanol. The reduction is conducted in dry tetrahydrofuran at a temperature below about -50° C. using equimolar quantities of the ketone compound and reducing agent.

Reducing agents such as lithium borohydride, diisobutylaluminum hydride or lithium aluminum hydride which can also be used, require anhydrous conditions and non-hydroxylic solvents, such as 1,2-dimethoxyethane, tetrahydrofuran, diethyl ether, dimethyl ether of ethylene glycol.

The cycloalkanols of formula I wherein OR₁ is hydroxy can, of course, be obtained directly by catalytic reduction of the protected cycloalkanone over palladium-on-carbon or by catalytic reduction or chemical reduction of the unprotected cycloalkanone (formula II, OR₁ =OH) using the reducing agents described above.

In actual practice it is preferred to produce the unprotected cycloalkanols of formula I (OR₁ =OH) via reduction of the benzyl protected cycloalkanones (OR₁ =benzyloxy) as described above, since it permits stereochemical control of the reduction and formation of the cis-hydroxy epimer as the major product and thus facilitates separation and purification of the epimeric alcohols.

Compounds wherein R₂ ' is alkenyl are transformed to corresponding hydroxyalkyl derivatives via hydroboration-oxidation using borane in tetrahydrofuran or diethyleneglycol dimethyl ether (diglyme) at 0° to 50° C. The intermediate borane product is not isolated but is directly oxidized with alkaline hydrogen peroxide to the alcohol. The alcohols thus produced correspond to anti-Markovnikov addition of the elements of water to the double bond.

Further, hydroxyalkyl derivatives can also be produced by oxymercuration-demercuration using mercuric acetate in water followed by reduction (sodium borohydride) of the intermediate hydroxy mecurial derivative. The reaction is carried out at ambient temperature using an aqueous mercuric acetate/tetrahydrofuran medium. The intermediate is not separated, but is reduced in situ to the alcohol. Addition occurs opposite to that of the hydroboration-oxidation reaction; namely, Markovnikov addition, the elements of water being added to the double bond in a manner opposite to that of the hydroboration-oxidation reaction to produce secondary alcohols.

The alcohols srrve as intermediates for production of corresponding aldehydes and ketones (oxoalkyl compounds) by oxidation with a suitable oxidizing agent such as pyridinium chlorochromate. The resulting oxo compounds in turn serve as intermediates for increasing the chain length of R₂ or R₃ alkyl groups having said oxo functionality and, of course, for introducing branching into said alkyl group. The Wittig reaction, using the appropriate ylide, serves admirably for this purpose. For example, reaction of an oxoalkyl group with triphenylphosphonium methylide converts the oxo group to a methylene (═CH₂) group. Hydroboration-oxidation, affords a primary or secondary alcohol, itself a useful intermediate.

Formulae I and II compounds wherein R₂ or R₃ is oxo substituted alkyl are conveniently prepared by oxidation of corresponding compounds wherein R₂ ' or R₃ is an alkenyl group having one more carbon atom than R₂ or R₃. Sndium metaperiodate and a catalytic amount of osmium tetroxide in aqueous tetrahydrofuran or dioxane at ambient temperature is favored as oxidizing agent since it tends to minimize oxidation beyond the aldehyde stage. However, despite its relative mildness as an oxidant compared to, for example, sodium metaperiodate/potassium permanganate, some oxidation to the corresponding acid and the corresponding hydroxy ketone does occur.

They can also be prepared by Grignard reaction of the appropriate 4-(acetal or ketal substituted alkyl)-2-cycloalken-1-one with the appropriate 2-bromo-5-(Z-W substituted)phenol according to the procedure described above. The acetal or ketal group is then transformed by treatment with acid, e.g., a mineral acid such as HCl, to the oxo group.

A favored procedure for preparation of compounds of formulae I and II wherein Z-W is --O--(alk₂)--W comprises selective alkylation of the appropriate 3-(2,4-dihydroxyphenyl)-4-(R₂ '-substituted)-2-cycloalkan-1-one in a reaction-inert solvent according to the procedure described below. The 3-(2,4-dibenzyloxyphenyl)-4-(R₂ '-substituted)-cycloalkanone is then, if no transformations are to be carried out on the R₂ '-group, debenzylated via hydrogen over palladium-on-charcoal to the corresponding 3-(2,4-dihydroxyphenyl)-4-(R₂ '-substituted)cycloalkanone and then converted to a ketal.

Ketal formation is accomplished according to well-known procedures for ketalization, such as reaction of said 3-(2,4-dihydroxyphenyl)cycloalkanone with an alcohol, especially an alcohol having from one to four carbon atoms, in the presence of an acid, such as sulfuric acid, p-toluenesulfonic acid, hydrogen chloride, under conditions which remove the by-product water. A favored procedure comprises reaction of said 3-(2,4-dihydroxyphenyl)cycloalkanone with an orthoformic ester in solution in an alcohol corresponding to the alcohol moiety of the orthoformic ester. Trimethyl orthoformate and methanol are favored reactants along with concentrated sulfuric acid, anhydrous hydrogen chloride, or ammonium chloride as catalyst.

The ketal thus produced is then alkylated by reaction with an appropriate alkylating agent such as W-Z-X" wherein W and Z are as defined above, and X" is selected from the group consisting of chloro, bromo, mesyloxy (CH₃ --SO₂ --O) and tosyloxy (p-CH₃ --C₆ H₄ --SO₂ --O) in the presence of an acid acceptor, e.g., sodium or potassium carbonate. The alkylated ketal is then deketalized by treatment with aqueous acid according to known procedures.

The 3-[2-hydroxy-4-(--O--(alk₂)-W-substituted)phenyl]-4-(R₂ '-substituted)cycloalkanones thus produced are converted to corresponding cycloalkanols by procedures described above.

When transformations are to be conducted on group R₂ ' as precursor to group R₂, e.g., alkenyl to hydroxyalkyl; --CH(OCH₃)₂ to --CHO; the desired transformations are carried out prior to removal of the protective, i.e., benzyl groups. For example, when R₂ ' is alkenyl, said group is hydrated via the hydroboration-oxidation procedure described above, either by direct conversion from the 3-(2,4-dibenzyloxyphenyl)-4-(2-propenyl)cycloalkanone, or by first converting the ketone to a ketal, followed by hydration of the propenyl group and the deketalization.

Formula I and II compounds wherein R₂ is oxo substituted alkyl serve as intermediates for preparation of oxo substituted alkyl derivatives having increased chain length via the Wittig reaction. A representative procedure comprises, for example, reacting an appropriate 2-(1,3-dioxolan-2-yl)alkyl triphenylphosphonium bromide at about 10° C. to about 80° C. with sodium dimsylate in dimethyl sulfoxide to generate the corresponding ylide in situ. To the thus produced ylide is then added an appropriate reactant such as 3-(2-benzyloxy-4-(Z-W substituted)phenyl-4-(2-oxoethyl)cycloalkanone ethylene ketal in a suitable solvent such as dimethyl sulfoxide at a temperature of from about 10° C. to about 80° C. The product, a 3-(2-benzyloxy-4-(Z-W substituted)phenyl)-4-(ω-oxoalk-2-enyl)cycloalkanone bis ethylene ketal, is recovered by known methods such as extraction and column chromatography on silica gel. In this Wittig reaction, the oxo group of the cycloalkanone moiety is protected by conversion to a ketal. If desired, the product is subjected to acid hydrolysis to regenerate the oxo groups. However, when the product is to be subjected to further reactions, it is advantageous to retain the bis ethylene ketal protecting groups on the product.

Reduction of the protected (ω-oxoalkenyl) group (R₂) of the thus produced compounds using catalytic hydrogenation over a noble metal catalyst, e.g., Pd/C, affords the corresponding protected (ω-oxoalkyl) compound. Treatment of the reduced product with aqueous acid (HCl) as described herein provides the ω-oxoalkyl derivative of formula II wherein R₂ is ω-oxoalkyl. Sodium borohydride reduction affords a formula I compound wherein R₂ is ω-hydroxyalkyl and R is hydroxy. The ω-hydroxyalkyl group can be converted to an ether group by the Williamson Synthesis which comprises converting the alcohol to an alkali metal alkoxide followed by alkylation of said alkoxide with an alkyl halide or alkyl sulfate.

Formation of a secondary alcohol group in R₂ is readily achieved by Grignard reaction on an appropriate compound of formula II, the 1-oxo group of which is protected as an alkylene ketal, and in which R₂ is oxoalkyl.

Compounds wherein R₂ is carboalkoxy substituted alkyl are prepared via the Wittig reaction using the appropriate protected compound of formula II wherein R₂ is oxo substituted alkyl; i.e., an aldehyde or ketone group, and a trialkyl phosphonoacetate such as trimethyl or triethyl phosphonoacetate. The reaction is carried out in a reaction-inert solvent such as diethyl ether or tetrahydrofuran at ambient temperature using about one mole of aldehyde reactant to two moles of trialkyl phosphonoacetate. A proton acceptor such as sodium hydride, about ten mole per cent in excess of the trialkyl phosphonoacetate is used. The alpha, beta-unsaturated carboxylic ester thus produced is then reduced, for example, by catalytic hydrogenation over Pd/C to provide the desired carboalkoxyalkyl derivative.

Alternatively, said compounds are produced by using a carboalkoxymethylene triphenylphosphorane in place of a trialkylphosphonoacetate. In such instances, the reaction is conducted in a reaction-inert solvent such as diethyl ether, tetrahydrofuran or methylene chloride at from about 20° C. to 80° C. A proton acceptor, e.g., n-butyllithium or phenyllithium is generally used. The alpha, beta-unsaturated carboxylic ester thus produced is reduced as before to give the formula I compound wherein R₂ is carbalkoxyalkyl. Hydrolysis, more desirably, saponification, using dilute (e.g., 6N) sodium hydroxide at reflux, followed by acidification, affords the corresponding carboxyalkyl compound.

Compounds wherein R₂ is carbamoylalkyl or substituted carbamoylalkyl are prepared in like manner using the appropriate carbamoylmethylenetriphenylphosphorane in a reaction-inert solvent such as methylene chloride at reflux to provide the alpha, beta-unsaturated carboxylic acid amide which is then reduced (H₂, Pd/C) to the corresponding carbamoylalkyl derivative. By choice of the appropriate oxoalkyl derivative of formula I, carbalkoxyalkyl and carbamoylalkyl derivatives of varying chain length are produced.

Alternatively, said carbamoylalkyl derivatives are prepared by ammonolysis of the corresponding carbalkoxyalkyl derivative with the appropriate amine, HNR₇ R₈, in a reaction-inert solvent. The temperature of the reaction depends upon the ester and amine reactants but ranges from room temperature to the reflux temperature of the solvent. In certain instances, the use of sealed tubes and elevated (e.g., reflux) temperatures are beneficial. However, satisfactory conditions for a given reaction are readily determined by simple experimentation. Representative solvents for this reaction are water, C₁₋₄ alcohols and excess of the chosen amine.

Still further, the carbamoylalkyl derivatives are prepared from corresponding carboxyalkyl derivatives via conversion of said derivatives to acid chlorides by reaction with thionyl chloride, phosphorous pentachloride or trichloride. Reaction with thionyl chloride is favored since the by-products are gaseous and easily removed. In general, excess thionyl chloride is used to serve as solvent as well as reactant and the reaction carried out at a temperature of 20°-100° C. Acylation of the appropriate amine (HNR₇ R₈) in a suitable solvent, e.g., water, by the Schotten-Baumann method; or in non-aqueous systems, e.g., tetrahydrofuran, dioxan, methylene chloride, in the presence of a tertiary amine (triethylamine, N-methylaniline). In either case, a temperature of from about 0° to about 50° C. is used.

Compounds of formulae I and II wherein Y is --CH(R₃)CH₂ -- are prepared via the previously described Grignard reaction from the appropriate 5-[2-benzyloxy-4-(Z-W substituted)phenyl]-2-cycloalken-1-ones, the preparation of which are described in Belgian Patent No. 870,404, published Mar. 12, 1979. Nucleophilic addition of the elements of HCN to said 2-cycloalken-1-one compounds by reaction thereof with aqueous sodium or potassium cyanide affords the corresponding trans-3-[2-benzyloxy-4-(Z-W substituted)phenyl]-5-cyano cycloalkanones which are valuable intermediates. Reduction of the oxo group of the cycloalkanone moiety by means of sodium borohydride yields the corresponding transcis hydroxy compound. It is converted to the corresponding trans-trans compound by refluxing in t-butanol solution in the presence of potassium t-butoxide.

The stereoisomeric cis-3[2-benzyloxy-4-(Z-W substituted)phenyl]-cis-5-cyanocycloalkanols are prepared by oxidation of the trans-trans stereoisomers using, for example, Jones' reagent followed by sodium borohydride reduction of the thus-produced cis-3-[2-benzyloxy-4-(Z-W substiuuted)phenyl]-5-cyanocycloalkanone.

Each of the above-mentioned 5-cyanocycloalkanol derivatives is also a valuable intermediate. The cyano group is readily converted by reduction with diisobutyl aluminum hydride (DIBAL-H) to the corresponding formyl derivative. The procedure comprises reacting the cyano derivative with DIBAL-H, two equivalents, in toluene at a low temperature, e.g., 0° C. to -65° C., followed by treating the reaction with dilute acid, e.g., a mineral acid such as sulfuric acid. The formyl derivative is recovered by standard procedures such as extraction with ether and evaporation of the solvent. Reduction of the formyl derivative, e.g., by sodium borohydride, affords the corresponding hydroxymethyl derivative. In the above reactions the benzyl ether derivative of the 3-(2-hydroxy-4-(Z-W substituted)phenyl)-5-cyanocycloalkanol is used as reactant in order to avoid reactions at the phenolic hydroxy group. The protecting benzyl group is rmmoved by methods described above.

The 5-hydroxymethyl and 5-formyl derivatives serve as intermediates to other values of R₃ by means of the reactions described above as regards conversion of hydroxyalkyl and oxoalkyl values of R₂.

Formula I compounds wherein R is hydrogen are prepared from the corresponding compounds of formula II by first converting the oxo group to a hydrazone (or semicarbazone) and then decomposing said hydrazone (or semicarbazone) by alkali such as sodium or potassium hydroxide, to produce the corresponding hydrocarbon derivative. The process is readily carried out by heating a mixture of the appropriate cycloalkanone compound and hydrazine hydrate in a reaction-inert solvent such as ethylene glycol or triethylene glycol at 100° C. Solid potassium (or sodium) hydroxide is then added and the mixture heated at an elevated temperature, e.g., 150°-200° C. It is then cooled, acidified and the product recovered by known methods, e.g., by extraction with ether.

Compounds of this invention wherein R₂ or R₃ is amino substituted alkyl are prepared from the corresponding compounds wherein R₂ or R₃ are oxo substituted alkyl. One procedure comprises converting the appropriate oxo compound of formula I or II to the corresponding oxime or oxime derivative; e.g., an alkyl ether or an acetyl derivative, followed by reduction of the oxime or derivative thereof to the desired amine. Of course, when a compound of formula II is used as reactant, the 1-oxo group must be protected to avoid reaction at that site unless introduction of an amino group at said site is also desired. The ketal group is a preferred protecting group because of the ease of preparation of said compounds and the relative ease of removal of said group to regenerate the oxo group.

The oximes of formulae I and II compounds wherein R₂ or R₃ is oxo substituted alkyl are prepared by reacting said compounds with hydroxylamine hydrochloride in a solution of methanol-water at room temperature. In practice, it is preferred to use an excess of hydroxylamine, up to as much as a three fold excess. Under such conditions the preparation of the dssired oxime derivative is complete in 1 to 2 hours. The product is isolated by addition of the reaction mixture to water followed by basification to pH 9.5 and extraction with a water-immiscible solvent such as ethyl acetate.

The oxime or oxime derivative is then reduced catalytically using, for example, Raney nickel, palladium-on-charcoal or platinum oxide at an initial hydrogen pressure of about 2-3 atmospheres at ambient temperature in a reaction-inert solvent such as C₁₋₄ alkanol, or lithium aluminum hydride in a reaction-invert solvent such as tetrahydrofuran at reflux temperature.

A still further procedure comprises the Gabriel synthesis in which potassium phthalimide is reacted with a compound of formula I or II wherein R₂ or R₃ is halo(Br, I)alkyl and the resulting phthalimide derivative hydrolyzed with a base such as sodium or potassium hydroxide or hydrazine. The halo alkyl compounds of formulae I and II are prepared by reaction of the corresponding hydroxy compound with the appropriate phosphorous halide or hydrogen halide.

A favored procedure for preparing said amino compounds comprises condensation of the appropriate formula I or II compound wherein R₂ or R₃ is oxo-substituted alkyl with the ammonium salt of a lower alkanoic acid and subsequent reduction of the in situ generated imine. In addition to lower alkanoic acid ammonium salts, ammonium salts of inorganic acids can also be used in this procedure.

In practice, a solution of the appropriate oxoalkyl compound in a lower alkanol such as methanol is treated with an ammonium salt of an alkanoic acid such as acetic acid and the cooled reaction mixture treated with the reducing agent sodium cyanoborohydride. The reaction is allowed to proceed at room temperature for several hours, and is sbbsequently hydrolyzed and the product isolated.

Although stoichiometric proportions of ketone and ammonium alkanoate are required, it is advantageous to use up to a ten fold excess of ammonium alkanoate in order to ensure rapid formation of the imine. It is also advantageous to conduct the reduction at ambient temperature and to use two moles of sodium cyanoborohydride per mole of ketone reactant in order to maximize the yield of the final product. Reaction is complete in 2-3 hours.

Reduction of the imine can, of course, be carried out with other reducing agents such as palladium-on-charcoal. In practice, a solution of the appropriate ketone in a lower alkanol, such as methanol or isopropanol, is treated with an ammonium alkanoate, such as ammonium acetate, and 10% palladium-on-charcoal, and the resulting suspension shaken in a hydrogen atmosphere at temperatures of about 25°-50° C. until the theoretical amount of hydrogen has been absorbed. It is preferred that a 10 fold excess of the ammonium alkanoate be employed to ensure complete reaction in a reasonable time period. The amount of the catalyst can vary from 10% to 50% on a weight basis, of the starting ketone. The initial pressure of the hydrogen is not critical, and a pressure from one to fifty atmospheres is preferred to shorten the reaction time. Employing the aforementioned parameters, the reaction time will vary between 2 to 6 hours. Upon completion of the reductive amination reaction, the spent catalyst is filtered and the filtrate concentrated to dryness.

The amino compounds produced by the above procedures are isolated by taking advantage of their basic nature which permits convenient separation from non-basic by-products and reactants. In general, an aqueous solution of the product is extracted over a range of gradually increasing pH so that non-basic materials are removed at the lower pH's and the product at a pH of about 9. The extracting solvents, e.g., ethyl acetate, diethyl ether, are back-washed with brine and water, dried and evaporated to give the product.

A further favored procedure comprises reaction of the appropriate compound of formula I or II wherein R₂ or R₃ is ω-hydroxy substituted alkyl with equimolar quantities of phthalimide, triphenylphosphine and diethylazodicarboxylate.

Compounds of this invention of Formula I wherein R is amino are prepared in like manner from formula I or II compounds. If either of R₂ or R₃ is oxo-substituted alkyl and introduction of an amino group at the 1-position of the cycloalkyl moiety is desired, said oxo group must be protected as by ketal formation. When amino groups are to be introduced simultaneously into the 1-position of the cycloalkyl moiety and R₂ (or R₃), the above-described processes are used but, of course, doubling the molar proportions of reactants per mole of oxo-containing reactant.

Mono- and dialkylamino substituted alkyl derivatives (R₂, R₃) of formulae I and II compounds are prepared by reductive alkylation of the corresponding aminoalkyl derivatives with the appropriate aldehyde or ketone in the presence of a reducing agent such as molecular hydrogen and a catalyst (Pd or Raney nickel) or nascent hydrogen from a metal-acid combination. When mono- or dimethylamino derivatives are desired, the Leuckart reaction, in which formic acid or one of its derivatives, such as ammonium formate, serve as reducing agent, is used.

It has been found that the compound of formula I wherein R is OH; R₂ is . . . (CH₂)₃ OH, --ZW is --C(CH₃)₂ (CH₂)₅ CH₃ and R₁ is benzyl (C₇ H₇) can be resolved into diastereomers A and B by reaction with d-mandelic acid and p-toluenesulfonic acid in benzene with azeotropic removal of water. Hydrolysis of the bis-d-mandelate esters of diastereomers A and B (e.g., K₂ CO₃ in methanol-water) affords enantiomers A and B.

In like manner, reaction of enantiomer B with 1-mandelic acid and p-toluenesulfonic acid in benzene with azeotropic removal of water affords diastereomer A of the bis-1-mandelate derivative. Hydrolysis as described above affords enantiomer B. Removal of the protecting benzyl groups affords the corresponding enantiomeric alcohols.

Similarly, the benzyl ether of the above-mentioned compound (R₂ =. . . (CH₂)₃ --O--C₇ H₇) is resolved into its diastereomers and enantiomers. Other compounds of formula I herein are also resolved in like manner.

Compounds of formulae I and II wherein R₂ and R₃ are alkyl substituted with --SR₆, --S(O)R₆ or --S(O)₂ R₆ are also active as CNS agents and antiemetics and are used in the same manner as are the formulae I and II compounds described herein. Said compounds wherein the alkyl substituent is --SR₆ are prepared from corresponding alcohols via halogenation (SOCl₂) and reaction of the thus produced chloride with HSR₆ in the presence of a base. Oxidation of the --SR₆ -substituted alkyl group with one or two equivalents of hydrogen peroxide or a peracid, e.g., m-chlor-perbenzoic acid, affords the corresponding sulfoxide or sulfone.

Acyl derivatives of formulae I and II compounds wherein R₁ is hydroxy and any of R, R₂ or R₃ is hydroxy, amino, or hydroxyalkyl or aminoalkyl are prepared by acylation with the appropriate alkanoic acid in the presence of a condensing agent such as dicyclohexylcarbodiimide, or by reaction with the appropriate alkanoic acid chloride or anhydride in the presence of a base such as pyridine. The order of reactivity of the acylatable R, R₁, R₂ and R₃ groups which are or which contain a hydroxy group is primary alcoholic OH, phenolic OH, secondary OH.

Esters of compounds of formulae I and II wherein R is hydroxy, OR₁ is hydroxy and R₂ or R₃ contain no acylatable group, are prepared by acylation according to the above-described procedures. Compounds in which only the R group is acylated are obtained by mild hydrolysis of the corresponding diacyl derivative, advantage being taken of the greater ease of hydrolysis of the phenolic acyl group.

The analgesic properties of the compounds of this invention are determined by tests using nociceptive stimuli. It is noted that compounds of formulae I and II wherein R₁ is benzyl are not pharmacologically active for the purposes described herein but are useful as intermediates for said compounds wherein R₁ is hydrogen.

Tests Using Thermal Nociceptive Stimuli

(a) Mouse Hot Plate Analgesic Testing

The method used is modified after Woolfe and MacDonald, J. Pharmacol. Exp. Ther., 80, 300-307 (1944). A controlled heat stimulus is applied to the feet of mice on a 1/8-inch thick aluminum plate. A 250 watt reflector infrared heat lamp is placed under the bottom of the aluminum plate. A thermal regulator, connected to thermistors on the plate surface, programs the heat lamp to maintain a constant temperature of 57° C. Each mouse is dropped into a glass cylinder (61/2-inch diameter) resting on the hot plate, and timing is begun when the animal's feet touch the plate. The mouse is observed at 0.5 and 2 hours after treatment with the test compound for the first "flicking" movements of one or both hind feet, or until 10 seconds elapse without such movements. Morphine has an MPE₅₀ =4-5.6 mg./kg. (s.c.).

(b) Mouse Tail Flick Analgesic Testing

Tail flick testing in mice is modified after D'Amour and Smith, J. Pharmacol Exp. Ther., 72, 74-79 (1941) using controlled high intensity heat applied to the tail. Each mouse is placed in a snug-fitting metal cylinder, with the tail protruding through one end. This cylinder is arranged so that the tail lies flat over a concealed heat lamp. At the onset of testing, an aluminum flag over the lamp is drawn back, allowing the light beam to pass through the slit and focus onto the end of the tail. A timer is simultaneously activated. The latency of a sudden flick of the tail is ascertained. Untreated mice usually react within 3-4 seconds after exposure to the lamp. The end point for protection is 10 seconds. Each mouse is tested at 0.5 and 2 hours after treatment with morphine and the test compound. Morphine has an MPE₅₀ of 3.2-5.6 mg./kg. (s.c.).

(c) Tail Immersion Procedure

The method is a modification of the receptacle procedure developed by Benbasset, et al., Arch. int. Pharmacodyn., 122, 434 (1959). Male albino mice (19-21 g.) of the Charles River CD-1 strain are weighed and marked for identification. Five animals are normally used in each drug treatment group with each animal serving as its own control. For general screening purposes, new test agents are first administered at a dose of 56 mg./kg. intraperitoneally or subcutaneously, delivered in a volume of 10 ml./kg. Preceding drug treatment and a 0.5 and 2 hours post drug, each animal is placed in the cylinder. Each cylinder is provided with holes to allow for adequate ventilation and is closed by a round nylon plug through which the animal's tail protrudes. The cylinder is held in an upright position and the tail is completely immersed in the constant temperature waterbath (56° C.). The endpoint for each trial is an energetic jerk or twitch of the tail coupled with a motor response. In some cases, the endpoint may be less vigorous post drug. To prevent undue tissue damage, the trial is terminated and the tail removed from the waterbath within 10 seconds. The response latency is recorded in seconds to the nearest 0.5 second. A vehicle control and a standard of known potency are tested concurrently with screening candidates. If the activity of a test agent has not returned to baseline values at the 2-hour testing point, response latencies are determined at 4 and 6 hours. A final measurement is made at 24 hours if activity is still observed at the end of the test day.

Test Using Chemical Nociceptive Stimuli Suppression of Phenylbenzoquinone Irritant-Induced Writhing

Groups of 5 Carworth Farms CF-1 mice are pretreated subcutaneously or orally with saline, morphine, codeine or the test compound. Twenty minutes (if treated subcutaneously) or fifty minutes (if treated orally) later, each group is treated with intraperitoneal injection of phenylbenzoquinone, an irritant known to produce abdominal contractions. The mice are observed for 5 minutes for the presence or absence of writhing starting 5 minutes after the injection of the irritant. MPE₅₀ 's of the drug pretreatments in blocking writhing are ascertained.

Tests Using Pressure Nociceptive Stimuli Effect on the Haffner Tail Pinch Procedure

A modification of the procedure of Haffner, Experimentelle Prufung Schmerzstillender. Deutch Med. Wschr., 55, 731-732 (1929) is used to ascertain the effects of the test compound on aggressive attacking responses elicited by a stimulus pinching the tail. Male albino rats (50-60 g.) of the Charles River (Sprague-Dawley) CD strain are used. Prior to drug treatment, and again at 0.5, 1, 2 and 3 hours after treatment, a Johns Hopkins 2.5-inch "bulldog" clamp is clamped onto the root of the rat's tail. The endpoint at each trial is clear attacking and biting behavior directed toward the offending stimulus, with the latency for attack recorded in seconds. The clamp is removed in 30 seconds if attacking has not yet occurred, and the latency of response is recorded as 30 seconds. Morphine is active at 17.8 mg./kg. (i.p.).

Tests Using Electrical Nociceptive Stimuli The "Flinch-Jump" Test

A modification of the flinch-jump procedure of Tenen, Psychopharmacologia, 12, 278-285 (1968) is used for determining pain thresholds. Male albino rats (175-200 g.) of the Charles River (Sprague-Dawley) CD strain are used. Prior to receiving the drug, the feet of each rat are dipped into a 20% glycerol/saline solution. The animals are then placed in a chamber and presented with a series of 1-second shocks to the feet which are delivered in increasing intensity at 30-second intervals. These intensities are 0.26, 0.39, 0.52, 0.78, 1.05, 1.31, 1.58, 1.86, 2.13, 2.42, 2.72 and 3.04 mA. Each animal's behavior is rated for the presence of (a) flinch, (b) squeak and (c) jump or rapid forward movement at shock onset. Single upward series of shock intensities are presented to each rat just prior to, and at 0.5, 2, 4 and 24 hours subsequent to drug treatment.

Results of the above tests are recorded as percent maximum possible effect (%MPE). The %MPE of each group is statistically compared to the %MPE of the standard and the predrug control values The %MPE is calculated as follows: ##EQU1##

The compounds of this invention, when used as analgesics via oral or parenteral administration, are conveniently administered in composition form. Such compositions include a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practices. For example, they can be administered in the form of tablets, pills, powders or granules containing such excipients as starch, milk sugar, certain types of clay, etc. They can be administered in capsules, in admixtures with the same or equivalent excipients. They can also be administered in the form of oral suspensions, solutions, emulsions, syrups and elixirs which may contain flavoring and coloring agents. For oral administration of the therapeutic agents of this invention, tablets or capsules containing from about 0.01 to about 100 mg. are suitable for most applications.

By means of the above procedures, the analgesic activity of several compounds of this invention is determined. The compounds have the formula shown below:

The antiemetic properties of the compounds of formulae I and II are determined in unanesthetized unrestrained cats according to the procedure described in Proc. Soc. Exptl. Biol. and Med., 160, 437-440 (1979).

The compounds of the present invention are active antiemetics via oral and parenteral administration and are conveniently administered in composition form. Such compositions include a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice. For example, they may be administered in the form of tablets, pills, powders or granules containing such excipients as starch, milk sugar, certain types of clay, etc. They may be administered in capsules, in admixtures with the same or equivalent excipients. They may also be administered in the form of oral suspensions, dispersions, solutions, emulsions, syrups and elixirs which may contain flavoring and coloring agents. For oral administration of the therapeutic agents of this invention, tablets or capsules containing from about 0.01 to about 100 mg. are suitable for most applications.

The physician will determine the dosage which will be most suitable for an individual patient and it will vary with the age, weight and response of the particular patient and the route of administration. Generally, however, the initial analgesic dosage in adults may range from about 0.1 to about 750 mg. per day in single or divided doses. In many instances, it is not necessary to exceed 100 mg. daily. The favored oral dosage range is from about 1.0 to about 300 mg./day; the preferred dose is from about 1.0 to about 50 mg./day. The favored parenteral dose is from about 0.1 to about 100 mg./day; the preferred range from about 0.1 to about 20 mg./day.

This invention also provides pharmaceutical compositions, including unit dosage forms, valuable for the use of the herein described compounds as analgesics and other utilities disclosed herein. The dosage form can be given in single or multiple doses, as previously noted, to achieve the daily dosage effective for a particular utility.

The compounds (drugs) described herein can be formulated for administration in solid or liquid form for oral or parenteral administration. Capsules containing drugs of this invention are prepared by mixing one part by weight of drug with nine parts of excipient such as starch or milk sugar and then loading the mixture into telescoping gelatin capsules such that each capsule contains 100 parts of the mixture. Tablets containing said compounds are prepared by compounding suitable mixtures of drug and standard ingredients used in preparing tablets, such as starch, binders and lubricants, such that each tablet contains from 0.10 to 100 mg. of drug per tablet.

EXAMPLE 1 Trans-3-[2-Benzyloxy-4-(1,1-dimethylheptyl)-phenyl]-4-(2-propenyl)cyclohexanone

A solution of 73.0 g. (0.188 mole) of 1-bromo-2-benzyloxy-4-(1,1-dimethylheptyl)benzene (BrZ') in 350 ml. of tetrahydrofuran was slowly added to 9.0 g. (0.375 mole) of 70-80 mesh magnesium metal. After a 5 minute initiation period the rate of addition was adjusted so as to just maintain reflux. The reaction was stirred 1.5 hours longer following completion of addition while cooling to 25° C. The reaction was cooled to -20° C. and 1.78 g. (9.38 mmoles) of cuprous iodide added. The resultant mixture was stirred 5 minutes and then a solution of 25.5 g. (0.188 mole) of 4-(2-propenyl)-2-cyclohexen-1-one (enone) in 30 ml. of tetrahydrofuran added dropwise while the reaction temperature was maintained at about -18° C. Additional 1.78 g. (9.38 mmoles) portions of cuprous iodide were added following addition of 1/3 and 2/3 of the enone reactant. The reaction was stirred 5 minutes longer at -20° C. and then added to 1000 ml. of ice cold saturated ammonium chloride. The quenched mixture was extracted with 1000 ml. of ether and the organic extract washed twice with 500 ml. of saturated ammonium chloride, once with 500 ml. of saturated sodium chloride, dried over magnesium sulfate and evaporated (aspirator) to an oil. The crude oil was purified via column chromatography on 1 kg. of silica gel eluted with 20% etherhexane to yield 58.3 g. (70%) of the title compound as an oil.

EXAMPLE 2 Cis-3-[2-Benzyloxy-4-(1,1-dimethylheptyl)phenyl]-trans-4-(2-propenyl)cyclohexanol and the trans, cis isomer

To a 0° C. solution of 14.3 g. (32.1 mmoles) of trans-3-[2-benzyloxy-4-(1,1-dimethYlheptyl)phenyl]-4-(2-propenyl)cyclohexanone in 50 ml. of methanol was added 1.22 g. (32.1 mmoles) of sodium borohydride. The reaction was stirred 30 minutes at 0° C. and then added to 500 ml. saturated sodium chloride and 300 ml. ether. The organic extract was washed twice with 500 ml. saturated sodium chloride, dried over magnesium sulfate and evaporated (aspirator) to an oil. The crude oil was purified via column chromatography on 200 g. of silica gel eluted with 2:1 pentane:ether to yield in order of elution 1.9 g. (13%) of the trans, cis-isomer of the title compound as an oil, 2.7 g. (19%) of a mixture of isomers and 7.3 g. (51%) of the title compound as an oil.

The products are converted to the corresponding ethylene ketals according to the procedure of Example 7.

EXAMPLE 61

The cycloalkanone compounds of Example 60 are reduced according to the procedure of Example 2 to provide the corresponding 3-[2-benzyloxy-4-(Z-W)phenyl]-4-(and 5)- substituted-cycloalkanols.

EXAMPLE 62

The cycloalkanols of Example 61 wherein Rx or Ry is alkenyl are hydrated according to the method of Example 5 to give the corresponding 3-[2-benzyloxy-4-(Z-W)phenyl]-4-(and 5)-ω-hydroxyalkylcycloalkanols.

Debenzylation of said compounds according to the catalytic hydrogenation procedure of Example 6 provides the corresponding phenols.

EXAMPLE 63

The cycloalkanone compounds of Example 60 wherein Rx or Ry is alkenyl are ketalized to their corresponding ethylene ketals by the procedure of Example 7 and then hydrated according to the procedure of Example 5 to produce the corresponding 3-[2-benzyloxy-4-(Z-W)phenyl]-4-(or 5)-(ω-hydroxyalkyl)cycloalkanone ethylene ketals. Catalytic hydrogenation according to the procedure of Example 6, followed by deketalization according to Example 8, affords the corresponding 3-[2-hydroxy-4-(Z-W)phenyl]-4-(or 5)-ω-(hydroxyalkyl)cycloalkanones.

EXAMPLE 64

Following the procedure of Example 9, the 3-[2-benzyloxy-4-(Z-W)phenyl]-4-(or 5)-alkenylcycloalkanones and cycloalkanols of Examples 60 and 61 are oxidized to give the corresponding compounds of the formula ##STR49## wherein ##STR50## is --OCH₂ CH₂ O-- or H, OH; s, Z and W are as defined in Examples 60 and 61; Rx or Ry represents the ω-oxoalkyl moiety having one less carbon in the alkyl group than does Rx or Ry of Examples 60 and 61.

Of course, in this example, the cycloalkanones are first ketalized according to the procedure of Example 7.

Also produced in this Example are corresponding compounds, wherein Rx or Ry is carboxyalkyl having two less carbon atoms in the alkyl group than does Rx or Ry; and the corresponding ω-hydroxyketones in which the unsaturated carbon atoms of the alkenyl moiety are converted to --CO--CH₂ OH.

Debenzylation of the thus-produced oxygenated products by the procedure of Example 6 provides the corresponding phenols. Deketalization of the ketals according to the method of Example 8 gives the corresponding cycloalkanones.

EXAMPLE 65

The procedure of Example 12 is used to convert the 3-[2-benzyloxy-4-(Z-W)phenyl]-4-(or 5)-1-(oxoalkyl)cycloalkanone ethylene ketals of Example 64 to the corresponding compounds wherein the 4-(or 5)-substituent is a secondary alcohol group. Deketalization of the products gives the cycloalkanones.

EXAMPLE 66

The ethylene ketal compounds of Example 60 wherein Rx or Ry is alkenyl and of Example 99 are converted to corresponding compounds wherein Rx or Ry is 4-(or 5)-ω-(1,3-dioxolan-2-yl)alk-2-enyl by the procedure of Example 10. Catalytic hydrogenation of said compounds according to the procedure of Example 11, followed by deketalization as per Example 8, affords 3-[2-benzyloxy-4-(Z-W)phenyl]-4-(or 5)-ω-(oxoalkyl)cycloalkanones wherein the oxoalkyl group contains 3 more carbon atoms than did group Rx or Ry.

EXAMPLE 67

The 3-[2-hydroxy-4-(Z-W)phenyl]-4-(and 5)-ω-(oxoalkyl)cycloalkanone ethylene ketals and cycloalkanols of Example 64 and 66 are converted to corresponding 4-(and 5)-ω-(aminoalkyl) derivatives by the procedure of Example 16. The products are isolated as their hydrochloride salts.

EXAMPLE 68

The compounds of Examples 60 and 61 wherein R₂ ' is dimethoxymethyl [--CH(OCH₃)₂ ] are converted to the corresponding formyl (CHO) compounds by the procedure of Example 17.

EXAMPLE 69

The procedures of Examples 19 and 21 are used to produce the following compounds from appropriate 3-[2-benzyloxy-4-(Z-W)phenyl]-4-(and 5)-ω-(oxoalkyl)cycloalkanols of Examples 17, 64, 68 and 104 and the appropriate dialkylphosphonoalkanoic acid esters.

EXAMPLE 70

The 3-[2-benzyloxy-4-(Z-W)phenyl]-4-(and 5)-ω-(oxoalkyl)cycloalkanols of Examples 17, 64, 68 and 104 are converted to corresponding 3-[2-hydroxy-4-(Z-W)phenyl]-4-(and 5)-ω-(carbamoylalkyl)cycloalkanols by the procedures of Examples 20 and 21 using, of course, the appropriate carbamoylalkylene triphenylphosphorane as the Wittig reagent.
